METALLIC BOX-BINDER.

SPECIFICATION forming part of Letters Patent No. 404,842, dated June 11, 1889.

Application filed October 16, 1888. Serial No. 288,255. (Model.)

To @ZZ whom, it may concern:

Be it known that I, FRANK G. JOHNSON, a citizen of the United States, residing in the city, county, and State of New York, have in-v vented a new and useful Metallic B0X-Binder, of which the following isa specification.

The object of my invention is to provide a box-binder for securing the corners of packing-boxes, which can be cheaply and conveniently applied by unskilled labor. l

The construction of my binder is fully set forth in the following specification, reference being had to the accompanyingdrawings, in which- Figure l represents a strip of sheet metal of which the binder is made, which may`vary in length, width, and thickness according to the character of the boxes to which the binders are to be applied. Fig. 2 shows the said strip as it is first bent in the process of making the binder, being bent three times at right angles to and upon itself on the diagonal lines aa ad aa. Fig. 3 shows the binder in a completed form, being further bent on the three converging lines b h b, and the two ends of the strip fastened together.., Fig. 4 represents the binder'fastened to a box B, as it appears when in use.

Similar letters refer to similar parts th roughout the several views.

A is a strip of sheet metal, similar to ordinary light-weight hoop-iron. This strip, in the process of making my binder, is first bent three times at suitable intervals over, upon, and at right angles to itself on the three dotted diagonal lines ad aa aa, which brings the said strip into the form shown by Fig. 2,

'enough to lap upon each other.

angles on the three cross-lines b b b, which said lines are perpendicular to the lines aa ad aa.

By this operation the two ends of the strip will meet, and if long enough will lap upon each other, and the three sides will stand at right angles to and incline toward each other, as shown in Fig. 3; or, in other words, the three sides form the surface of a frustum of an equilateral triangular pyramid-and lie in planes which are at right angles to each other. The binder is now completedsimply by fastening the two ends together with the rivet d, the said strip being cut and the ends left long The ends can be left sufficiently long to be bent and turned back upon themselves and hooked toget-her before they are riveted, as shown at c, Fig. 3.

My binder thus made its upon the corners i of any and every box having right angles.

Whatlclaim as new and useful, and desire to secure by Letters Patent, i9-

A box-binder consisting of a single Hat strip 0f sheet metal A, bent on the three diagonal lines ad aay da and on the three crosslines b b h, having three sidesat right angles to and inclined toward each other, and having the two ends of the said strip fastened together, as and for the purpose set forth.
